A, B	PF03888	MucB/RseB N-terminal domain (MucB_RseB)	MucB/RseB N-terminal domain	Members of this family are regulators of the anti-sigma E protein RseD.	Domain
C, D	PF03873	Anti sigma-E protein RseA, C-terminal domain (RseA_C)	Anti sigma-E protein RseA, C-terminal domain	Sigma-E is important for the induction of proteins involved in heat shock response. RseA binds sigma-E via its N-terminal domain, sequestering sigma-E and preventing transcription from heat-shock promoters [1]. The C-terminal domain is located in t ...	Sigma-E is important for the induction of proteins involved in heat shock response. RseA binds sigma-E via its N-terminal domain, sequestering sigma-E and preventing transcription from heat-shock promoters [1]. The C-terminal domain is located in the periplasm, and may interact with other protein that signal periplasmic stress.	Domain
